Train attack shows impossibility of tracking all Islamic militants

PARIS (AFP) – The thwarted attack by a gunman on a high-speed train between Amsterdam and Paris has underlined the difficulty faced by intelligence services in tracking the unprecedented numbers of potential Islamic militants, experts say.

The Moroccan suspect in Friday’s incident, identified as 25-year-old Ayoub El Khazzani, was first flagged by Spanish authorities as a potential extremist and had reportedly travelled to Syria.
